Help me learn to tune

Hi all,

I have a 1979 camaro with 350sbc (has a low lift cam) cam setting is 1. Idle, cruising and startup feels good.

I'm only bummed out that it burns rubber sometimes but not others. I've tried adjusting fast accel pump settings but it hasn't helped to much. Can someone take a look and suggest if I'm taking the right approach?

Right now accel pump and fast accel pump are set to 0 for all temps. Two logs linked below with idle and WOT. Looks like no evidence of lean tip in.. but I can't tell if this is overfueling or just lagging from not enough initial fuel. I am thinking fast accel needs increased.

All suggestions are appreciated.

Thanks,

Levi.
